deploying a green ip telephony network
DESCRIPTION
IP telephony can be greener today. Simple actions and smart methods for running IP telephones and ethernet switches repeated many times over make a big difference. Make power efficiency a buying criteria for IP phones and Ethernet switches. Design your network to use less power including 10/100M where more is not needed and using two-tier architecture instead of three tier when possible. Use switches for your IP telephones and deploy automated power saving modules to phone banks. Powering down phones during non-business hours will save 75% in electricity costs per office.TRANSCRIPT

Energy Saving Approaches
► Procure IP Telephones and Ethernet switches that use less power
► Design the network to use less power
► Intelligently optimize power to IP telephones

► Make power efficiency a buying criteria for IP Phones & Ethernetswitches • Product design, choice of internal machinery drives lower power consumption
• Environmental compliant products enable efficient recycling and reuse
► PoE capabilities enable efficient use in Ethernet-based networks • IP phone power requirements discovered with more granularity than PoE class
• Standard based protocols such as LLDP further industry-wide adoption

Design the Network to Use Less Power
► Use 10/100M where more is not needed
► Advanced IP Telephony with video can take advantage of Gigabit speeds
► 10/100M is sufficient for standard IP Telephony
Use fewer tiers where possible
► High density switches enable eliminating layers
► Many mid-Enterprise networks moving to 2-tier instead of 3-tier
Consolidate the Data Center
► Distributed server farms on the same campus can increase network bandwidth and equipment needs

Response: Trigger the application of the profiles to power off the IP handsets on specified edge ports.
Result: Power savings for phones, switch ports, and air conditioning. Reduction of energy costs and of carbon emissions.
Similar automation to power on before next shift.

Scenario: Office Building
200 person office
9 - 5, Monday - Friday for most workers
Yet, desk phones are powered 7x24
Identify 150 non-critical deskphones
Universal Port: power down at 6:00pm each evening, restart at 7:00am the next morning
Power savings over the weekend
Immediate 75% electricity savings – per office

Assume 25 school buildings K-12
Assume 50 desk phones per school –
1,250 phones total
Very light utilizationduring the summer months
Page 9
Scenario: School District –Summer Vacation
Assume 10 phones per school needed in the summer (250)
Universal Port: power down the other 1,000 desk-phonesfor the summer months
Automatically power them up, prior to school starting
80% power savings over the summer district wide
